While his body was destroyed in Hunte castle, Austria during the 1939 events of the Nazi space program, Von Klempt's head was kept alive in a life preseving jar. Able to attach to various robot bodies, or unaided flight, the twisted and evil Von Klempt still plots to preserve Nazi ideals through his insane schemes and inventions. He is never without his favourite creation - the Kriegaffe (war ape) by his side, although Hellboy continually destroys them.
